The Generator or Minimizer?

[zz]

Hi Stan, regarding minimizer and your future Generator filter I just wonder if it will be possible to do following: for example in Keno or a lottery game you chose several hundreds or thousands of 4 or more numbers combinations and you would like to cover them all just once with minimum possible number of 8 , 10 or more numbers combinations while applying some filters for example don't combine certain 4 numbers combinations together into these 8 or 10 numbers ones?

Or you think that numbers 20,23 and 25,44 will not show together , so since using just up to 3 of them don't combine together chosen 20,21,22,23 with 25,26, 44,48 into some of those 10 numbers combinations.

i don't think this will be possible. you'll have to do it in two steps - first generate your tickets from a given range while filtering out your unwanted 4 number combinations and then apply the minimizer.

the problem is that the minimizer and optimizer filters are a bit special because they need to randomly access all tickets they are filtering.
while other filters can reject/pass a ticket just by 'looking' at its numbers only, they don't need to know what the remaining tickets look like.

the filtered generator will work as follows:
1. generate next ticket in sequence
2. apply filters on this tickets and if it passed, write it into the package
3. continue with step 1 until all combinations are depleted

so as you can see the minimizer/optimizer filter will not work in this scenario as they don't have access to the tickets not generated yet.

the same applies to the planned 'compound filter' - it won't be possible to chain the minimizer/optimizer filter with other filters.

that's a job for the ticket numbers filter. when the filtered generator is ready you'll simple choose the number range and add two filters:
- reject tickets with numbers 20 and 23
- reject tickets with numbers 25 and 44

So basically, it is possible somehow to cover a thousand of chosen 4 numbers combinations just once for example with minimum necessary number of 10 numbers combinations?

well, the optimizer or minimizer can handle that but you have to provide a list of tickets that contain these 4 number combinations first. which of course could be e.g. a list of possible combinations from a given range.

other problem is that minimizer/optmizer always tries to cover all 4 number combinations from the given. it is not possible to select a subset of favorite quads/triplets and optimize the coverage for these only. is that what you're referring to?

on the other hand it wouldn't be that difficult to extend the two filters and provide an option to choose a custom list of combinations for coverage optimization.

Ok here is an example, just to make it clear. In 6/49 lottery is 18424 triples. So you think 15000 of them will not show in the very next draw, but you want to have a minimum possible number of 10 numbers combinations that will cover the rest of 3424 triplets just once. So the proper way so far should be make all 10 number combinations, filter these containing one or more of these 15000 triples, and apply minimizer ?

That would be a great feature..

that's correct - create all 10 number combinations, remove those tickets that contain any of the 15000 triplets, then apply the minimizer
